"Any animal that comes back to the right place after a long travel, or comes back to the same place again and again following a major movement, is amazing," said Martin Wikelski, a migration expert at the Max Planck Institute. (Read about great animal migrations in National Geographic magazine.)

Many animals have a built-in magnetic system, "like a regular compass," said Wikelski, who is also a National Geographic emerging explorer.

Wikelski tells us about five other animal species that are "super navigators" known to science, from eels to ants. Read about them at NatGeo News. Link-Thanks, Marilyn Terrell!
